MICHAEL J. BLESSING, or PROVIDENCE, RHODE ISLAND.

PIN.

Specification of Letters Patent.

Patented Feb. 2, 1909.

Application filed March 20, 1908. Serial No. 422,326.

To all whom it may concern:

Be it known that I, lViIOHAEL J. BLEssING, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Pins, of which the following is a'specification. My invention relates to fastening devices for pins, brooches, badges, and similar articles of personal adornment; but more particularly to the pin tongue or shaft thereof. Its objects are essentially simplicity, cheapness of construction, convenience in use, and adaptability to repair.

The invention consists in the novel construction hereinafter described and then pointed out in the claims.

In the drawings which form a part of this specification, Fi ures 1 and 2 are a side elevation and plan respectively of apin embodying my invention, and Fig 3, a seo tion of the same on line a: x of Fig. 2.

Like characters of reference indicate like parts throughout the views.

A represents the body orbase plate of an ordinary pin, and B the usual catch. Fixed by solder or otherwise to the face of the body, A, near the end opposite tothe catch, is a vertical post provided with a central longitudinal or axial opening, 0, extending through the post. The opening has screw threads, 0, throughout its length.

The pin tongue comprises a pointed shaft,

D, whose end, d, is bent at substantially right angles to its body. This projecting end is cylindrical in form and is provided with exterior screw threads, 01, which loosely engage the screw threads, 0 of the post. It is preferable that the bent end be somewhat shorter than the opening, 0, and that the screw threads, 01, not extend to the top ofv said opening.

The loose screw threaded connection of the parts permits a swiveling action of the pin tongue, D, to any desired position in a plane substantially parallel to the plane of the body, A, but prevents objectionable trans verse play or travel common in ball and The shaft slightly inclines, towards its point, away from the body and above the catch, to afford the required tension when engaged with the catch. This tension is preserved and augmented by the vertical post, 0. When, for the purpose of repair or substitution, it is desired to remove the tongue, the removal is consummated without fracture or removal of parts by merely rotating the pin shaft continuously towards the left.

The shaft, D, is prepared and mounted as follows: The screw threads, (1, are turned upon the shaft, D, before bending. By rotation to the right, the shaft enters the open ing, 0, the desired depth. The projecting portion of the shaft is then manually forced towards the pin body, A, imparting the required bend above the post.

What I claim is,

1. As a new article of manufacture, a pin tongue comprising a body portion, an end of the body bent at an angle to the body, and screw threads upon the bent end.

2. In a pin, the combination with the body and a post u on the body provided with a screw threade opening, of a pin tongue provided with a screw threaded end mounted in the opening.

3. In a pin, the combination with the body and a post upon the body provided with an axial opening and interior threads, of a pin tongue provided with an end bent at an angle to the remainder of the body and provided with screw threads engaging the screw threads of the post.

4. As an improved article of manufacture, a pin comprising a body, a post upon said body having an axial screw threaded opening, and a pin tongue rovided with an end bent at an angle to t e body and to the length of the pin, said bent end being screw threaded and removably and adjustably engaged in the opening of the post.

' 5. As an improved article of manufacture, a pin comprising a body, a post upon said body having an axial threaded opening, and a pin tongue provided with an end bent at an angle to the body and to the length of the pin, said bent end being threaded and r0- tatably removably and adjustably engaged in the o ening of the post, the screw threads of the ent end being confined within the post.

In testimony whereof I have aflixed my signature in presence of two witnesses.

MICHAEL J. BLESSING.
